This weekend we were diving with a good friend of mine who enlightened me on how to rinse my GoPro and other tiny diving gear with a tendency to get encrusted with salt.
Easy-peasy lemon squeezy:
Just place them in the tank of the toilet system! GENIUS! That way every time you flush, you get rid of the salty water and refill it with nice, fresh, clean water! And after a couple of days you have a sparkling GoPro.
This life hack has definitely made my weekend!
Thanks Jo!
